I stumbled upon dyno graphs for hp/torque conducted by TRD. The increases are most impressive with an unexpected bump from just over 2K rpm on up. Being a skeptic, I called them and spoke with a TRD engineer involved with R&D of "our" CAI and he assured me the data was acquired under controlled, repeatable conditions and represent an average of pulls with an OEM exhuast.
So I pulled the trigger and ordered one plus a spare filter and cleaning kit. It'll be here tomorrow and I'm starting to feel giddy already.
Here's the link, click on "Performance Comparisons" and check out the graphs:
The P/N is PTR05-35061. TRD says they're temporarily sold out. I got the last one available from my regional parts distribution center according to my Parts Mgr.
